The CNPC-1000 from Collins Aerospace is a Command-and-Control Data Link that operates from 960 to 977 MHz. It uses the Control and Non-Payload Communications (CNPC) waveform. The CNPC waveform provides command-and-control services between a control station and an unmanned aircraft, in addition to providing higher bandwidth weather radar and video downlink services.
The data link supports point-to-point modes between a single control station and a single unmanned aircraft, as well as network modes. The network modes enable positive handoffs of the aircraft between multiple control stations or multiple ground towers, and communications with multiple unmanned aircraft from a single ground data link. It can install in either the aircraft or the control station.
The CNPC-1000 operates within the L-band (growth to C-band) terrestrial aviation safety spectrum, cooperatively with ADS-B transponders and other systems operating simultaneously on the unmanned aircraft. It requires a DC supply of 14/28 V and draws under 8 W of power. The data link features RS-232 interface for external time input, RS-485 interface for controlling ancillary equipment and Ethernet interface. It has a frequency tuning resolution of 25 kHz.
The CNPC-1000 is available in a module that measures 14.02 x 7.39 x 2.11 cm and is suitable for unmanned aircraft system (UAS) operations in shared airspace. It provides control, telemetry and higher-bandwidth weather radar and video downlink services.
